PNEUMATIC CLEANING IMPLEMENT.

Specification of Letters Patent. Patented Feb. 14, 1911.

Application filed October 26, 1909. Serial No. 524,664.

To all whom may concern.

Be it known that I, R01 C. BAKER, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Masszvchusetts, have invented new and useful Improvements in PneumaticCleaning Im lements, of which the following is a speci oatioll.

This invention relates to improvements in pneumatic vacuum apparatus forcleaning carpets, floors, walls, draperies, and other surfaces, and theobject. is to provide a device combining in one implement a suction heador nozzle and a tool having means whereby the same is adapted to beeasily, quickly and conveniently attached to and detached from thesuction head, such" tool having thereon a brush, a felt pad or othersuitable device according to the nature of the surface to be cleaned.

The invention consists in the novel features of construction and in thecombination and arrangement of parts set forth in the followingspecification and particularly pointed out in the claims.

Referring to the drawings: Figure l is a plan of a tool forming a partof a pneumatic cleaning implement embodying my invention. Fig. 2 is afront elevation of the same. Fig. 3 is a vertical sectional view of thecomplete implement including the hollow suction head and the tool whichis attachably and detachably attached thereto, said tool having brushfiber or bristles thereon. Fig. 4 is a view similar to Fig. 3 exceptthat the tool is shown as provided with a pair of felt pads in place ofthe bristles.

Like numerals refer to like parts throughout the several views of thedrawings.

In the drawings, 5 is a hollow suction head or nozzle of suitable formhaving an inlet orifice (i and provided adjacent to said orilice withlaterally extending rounded heads 7 and 8 on opposite sides thereof.Embracing the suction head 5 is a tool 9, said tool having tworelatively movable parts 10 and 11 preferably provided, respectively,with grooves 12 and 13 which receive the beads 7 and 8, respectively.The two members 10 and 11 which may be formed of wood or other suitablematerial may be provided with any suitable pad or brush and in Figs. 2and 3 are shown as being provided with tufts of bristles 14, while inFig. at are shown as provided with felt pads 15. The two members 10 and11 are connected to each other by rods 16, 16 and for convenience ofmanufacture and assembling these rods consist of wood screws which arescrewed into the member 11 and have a sliding fit in the member 10.

Sin'rounding-the screws 16, res eetively, are sleeves 17 serving as ameansgor'limiting the movement of the members 10 and 11 toward eachother. Intel-posed between the heads of the screws 16, and the member 10may, if desired, be seated in recesses 19 proing to urge the members 10and 11 toward each other, or, in other words, serving as a resilientmeans to hold the tool 9 on the head 5 in such a manner as to render iteasy and convenient to attach the tool to the head and detach the sametherefrom.

In attaching the tool to the suction head, the two members 10 and 11 aresprung apart members being released and allowed to engage said head, asshown in Figs. 3 and 4:, with the heads 7 and 8 located in the grooves12 and 13, respectively, thus preventing accidental displacemcnt of thetool on the head. When thus assembled, the implement is passed to andfro over the surface to be cleansed, such as hard wood floors, walls andother hard surfaces and the dust is drawn into the suction head in theusual and well-known manner.

When it is desired to use the device for cleaning surfaces of carpets,rugs, draperies and other goods of like nature, the tool 9 is removedfrom the holder 5 and the head is to be cleaned and for this purpose thebeads 7 and 8 are rounded, as shown, so as to easily pass over thesurface being cleaned without injuring the same.

The means for attaching the tool to the head renders its removal andreplacement a matter of but a moment and is very convenientlyaccomplished as will be readily apparent.

Having thus described my invention, what 1 claim and desire by LettersPatent to secure is:

l. The combination, in a pneumatic cleaning implement, or a hollowsuction head havi an inlet orifice, and an attachable and etachable toolhaving two relatively movable parts embracing said head adjacent to saidorifice, said tool having resilient then used in direct contact with thearticle are helical compression springs 18 which vided in the member 10,these springs servand the head inserted thcrebetween, said' thereon and.ing com and reslhent ing implement, of a means to hold s aid arts incont-act with'.op-

posite sides of said cad.

2. The combination, in a pneumatic cleanhollow suction head having aninlet orifice, and an attachable and detachable tool having fibrousmaterial having two vresiliently connected parts yieldingly engagingopposite sides of said' head ad acent to said orifice.

- 3. The combination, in a pneumatic clean ing implement, of a,hollowsuction head havin an inlet orifice, and an attachable andetaehable tool having two relatively movable parts embraci said headadjacent to said orifice, said hea and said tool havlementaryinterengaging means,

means to hold said interengaging means in interengagement with eachother. 7

4:- The combination,

in a pneumatic clean.- ing implement, of a hollow suction head hav' aninlet orifice, and an attachable and etachable tool having tworelatively movable members engaging opposite sides of said head adjacentto said orifice, two rods connecting said members to each other, andsprings urging said members toward each other.

frods eonnectin said members 5. The con'lbination, in a pneumaticcleaning implement, of a hollow suction head having an inlet orifice,and an'attachable and detachable tool having two relatively movablemembers engaging opposite sides of said head adjacent to said orifice,two rods connecting said members to each other, means-tor lim ting themovement-of said members toward each other, and springs urging saidmembers toward each other.

The combination, in a pneumatic cleaning implement, of a hollow suctionhavin an inlet orifice, and an attachable and etaehable tool havingmovable members engaging opposite sides of said head'adjacent-to saidorifice, two

A to each other, tubes surrounding said rods, respectively,

head

two relatively adaptedto limit the movement'of said mom- 1 ber's towardeach other, and springs urging said members toward each other.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesscs. y
